SPECIFICATION forming part of Letters Patent No. 482,280, dated September 6, 1892. Application led Apn'l 5, 1892. Serial Nol 427,912. (No model.)

To all whom it may concern:

Be it known that I, GEORGE SOLARI, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Automatic'Sash-Fasteners, of which the following is a full, clear, and exact description. reference being had to the accompanying drawings, forming part of this specication.

This invention relates to a self-locking an tiburglar sash-fastener which has a hid lock and a hid trip-trigger bolt and spring-actuating device for effecting said lock, the said lock being embedded in the meeting-rails of the sash, and the concealed automatic tripping device being far removed from said lock, where it would be unsuspected by burglars, in the bottom of said sash, and the trip-bolt, as the sash closes, coming in contact with a metal boss-plate in the sill is thrown upv and trips a pawl from its ratchet-seat in thecircle stem of a quadrant-plate, which quadrant in its constrained ratchet-held position by means of a connecting-cord had previouslywithheld the spring-lock bolt from engagement, which bolt thus automatically released, locks the meeting-rails of the sash.

Figure I is an inside detail elevation ofthe automatically-locked window-sash with parts broken away to effect a larger view, and other parts broken away to show the embedded spring-lock fastening of the meeting-rails; also the trip-bolt, spring-pawl, ratchet-quadrant, the Captor-cord that connects said quadrant to the spring-bolt of ythe lock, and the pulley-wheel, around which said cord rides. Fig. II is a detail vertical section and shows the embedded spring-lock in its engaged position. Fig. III is a top view of the springlock with its inner casing-plate removed, and shows the quadrant backing-plate of the bolt with part broken away to show the moorage of its Captor-cord. It also shows the spring that enforces the engagement of the bolt when released by said captive cord and the keeperplate with its safety-box, into which said bolt is sprung and guarded. Fig. IV is a front view of the lock and shows the bolt sprung forward into its engaged position. Fig. V is a top view of the cap-plate. Fig. VI is a rear View of the lock and shows the spring mounted on its pedestal. Fig. VII is a perspective View of the spring-look bolt and integral quadrant backing-plate. Fig. VIII is a rear view of the automatic tripping device and shows the quadrant with part broken away to show the attachment of the Captor-cord that restrains the spring-lock bolt. It also shows the springpawl ratchet-lock of said quadrant, that in conjunction with said cord holds said lock-bolt captive in its unlocked position, as also the trip-bolt, which as it strikes the sill in the closing of the sash, trips said spring-pawl from its ratchet-hold of the quadrant, and thus releases the previously captive lock-bolt, whose spring then throws the saine into its locked position in the keeper. Fig. IX is a front view of the attachment-plate, which carries said tripping device and which is secured on the inside to one of the lower corners of the lower sash. It also shows the screw-set lock winding-key mounted on the axle that carries the quadrant, by which key said quadrant with its captive cord is turned to withdraw the springbolt of the lock, to release the sash for raising, and when the lock-bolt is thus withdrawn the spring-pawl and ratchet holds said quadrant and captive cord in their restraint of said bolt until when the sash again descends the automatic trip-bolt again throws up and releases said pawl. Fig. X is a bottom view ofthe boxing that carries said tripping device. Fig. XI is a side View of the quadrant, and shows its pawl, ratchet-seat and key-stem. Fig. XII is a modification of said quadrant and shows a keyhole-socket to its winding stern, and. Fig. XIII is a perspective view of a modiiication of the winding-key, which has a square stem that {its in the keyhole-socket shown in Fig. XII.

Referring to the drawings, l represents the window-frame, 2 the window-sill, 3 the sider'ails of the lower sash, 4 its base-rail, and 5 its meeting-rail.

6 are the side rails of the upper sash, and 7 is its meeting-rail.

8 represents the spring-lock that fastens the 'meeting-rails, and consequently locks both sashes. The boxing of said lock is constituted of the top boxing-plate 9, which is countersunk in the top of the meeting-rail 5 of the lower sash, to which it is secured by the screws l0, seated in the perforations ll, the integral facing-fiange 12 of said boxing-plate,

IOO

which is counter'sunk in the meeting face of said meeting-rail, to which it is secured by the screws 13, seated in the perforations 14,'

said plate and engages in the screw-socket of said pedestal.

2l represents the pivotal spring quadrantbolt of said 1ock,which is of a peculiar formation, having a quadrant-shapedbacking-plate 22 that insures a sufficient momentum to its movements and provides vantage ground for the attachment and Working of its various coad j utory parts. The arc-shaped bolt proper i 23 is integral with said quadrant-plate and Works in its throw and withdrawal through the slot-aperture 24 in the facing-ange 12. The said quadrant-plate is mounted and has its movements on the pivot-pedestal 25, which is pendent from the top boxing-plate 9 and is seated in its bearings 26 in said plate.

- 27 represents the spiral spring, which is mounted on the pedestal 19, and whose heel 28 is braced against the inner side of the facing-flange 12, and whose active arm 29 has its elastic drive-seat in and against the concave rear edge 30 of said quadrantplate, so as to enforce the locking-engagement of said bolt, except when it is held captive and restrained by the combined captor and trip cord 31, which cord is preferably made of brass wire but may be of any other suitable material, and is seated in the concave channel-groove 32 in the are edge of said quaddrant, and its end is passed through the perforation 33 in the quadrant and is knotted or otherwise secured at the outer end of said perforate seat.

34 represents the keepeinplate, which is countersunk at 35 in the inner edge of the meeting-rail of the upper sash and is there secured by the screws 36, which are seated in the perforations 37 in said keeper. The lockbolt 23 engages in the slot 38 in said keeper when it is sprung into locking-engagement, being seated in its safety box 81 of said keeper.

39 represents a channel-groove in the upper edge of the meeting-rail 5 of the lower sash and in the outside edge of one of the side rails 3 of said sash, and 40 is a pulley box on the journal-pin 4l of which the pulleywheel 42 is mounted. The said pulley-box and its pulley are coiintersunk at 43 in the upper outer corner of said side rail of the sash. In said channel-grooves 39 and around said pulley-wheel 42 the said captor-cord 3l is bedded and Works. i

44 represents the automatic tripping de vice, whose boxing front plate 45, facingiiange 46, box-rim flanges 47, screw-socket pedestal 48, pawl-journal pedestal 49, and trip-bolt-carrer lugs 50 are all cast or made integral. 0

51 represents an inner cap-plate, which is seated on the rim-flanges 47 and whose side notches 52 clamp onto the projecting lugs 53, and the screw 54, which is seated in th'e perforation 55 in said cap-plate, engages in the aforesaid screw-socket pedestal 48 and with the aid of said lugs 53 holds the cap-plate to the boxing it caps. The said boxing, which carries the captor and the trippingdevices that automatically spring the lock to fasten the sash, is countersunk at 56 in the inside lower corner ofthe sash beneath the cliannel-groove 39, and it is secured to said sash by screws which are seated in the perforations 57 in the `front plate 45 and are screw-seated in said sash.

I will now describe the captivating and automatic trip-releasing works located within 'said box. 58 represents the captor quadrant-plate,

Whose side journals 59 have their perfor-ate bearings 60 in the front plate 45 and in the inner cap-plate 51. 6l represents the arc shaped and grooved edge of said captor quadrant-plate, which along said circumferential surface said edge is grooved in a convex form `to make a bed for the combined captive andtrip end of the aforesaid captor-cord 31, whose extreme end passes through a perforation 62 in said quadrant-plate and is knotted at 63 or otherwise secured. The rear pivotal end of said quadrant-plate is of circumferential form 64 and bears a ratchet-toothed edge 65, in which in the unlocked position of the sash the point of the pawl 66 engages', which pawl is mounted on the aforesaid pivotal pedestal 49, and said pawl is held to said engagement with said ratchet-teeth by the spring 67, which IOO IIO

spring is secured to the rearof said pawl and its loose end engages against the upper rim of the box-flange 47.

68 represents the square key end,that projects beyond the enlarged round journal 59 in front of the bearing in the front plate 45, and 69 is the key whose square flange-seat 70 is seated on and embraces said key-head and is there secured by the set-screw 71.

In Fig. XII is shown a modification in which instead of said square keyhead a squaresocket keyhole 72 is made in said journal4shaft, in which the square stem 73 of the modified key 74 is seated.

75 represents the automatic pendent tripbolt, that passes through and Works in the slot 76 in the under flange 47 of the box, and its reduced elongated neck 77 between its shoulders 78 and head 79 is seated and works vertically between the aforesaid projecting carrier-lugs 50.

80 represents a metal boss or plate that is inlaid in the window-sill immediately ben eath the trip-bolt. The said boss may be, as shown in Fig. I, the head of a screw, which screw is inserted in said window-sill or other like device.

The operation of the device is as follows: Supposing the sash to be open and, consequently, unlocked, then the captor-cord, ratchet-toothed quadrant, spring-pawl, and automatic trip-bolt will be in the position shown in Fig. VIII. In said position the brass cap= tor-cord 3l, being held in stress by the pawlratchet and captive quadrant-plate, draws the captive pivoted quadrant plate 22 of the spring-lock, so as to withdrawits bolt 23 clear within the facing-plate l2 of said lock. When said open sash or window is closed, then the lower end of the trip-bolt 75 strikes the boss 8O in the window-sill, thus elevating said bolt and the spring-pawl 66, the point of which pawl is thustripped out of its ratchet-seat 65, and the pivoted Captor quadrant-plate 58, being itself released, releases its draft 'va the captor-cord on the pivoted-spring quadrant-bolt 2l, which latter is immediately precipitated by the spiral spring 27, so that its then projecting bolt 23 engages in the keeper ,34 in the corresponding meeting-rail 7, the

said bolt being housed and guarded from the intrusion of burglar-tools by the aforesaid safety-box 8l, against the arc turn 82 in which box said bolt also clamps to prevent the rattling of the meeting-rails.

Vhen it is required to again unlock the sash or window, the key 69 or the modiiied insertible key 7 4 is turned from the position shown in broken lines in Fig. IX to that shown in full lines in the same iigure, which action turns around the captor-quadrant 5S from the position shownin Fig. I to that shown in Fig. VIII, in which the pawl again engages in its ratchet-seat 65, and the captor-cord 3l again withdraws the pivoted captive quadrant-plate 22 of the lock and its bolt 23, so that the sashes can be respectively raised and lowered and the window opened.

The meeting-rails when in engagement are spring-locked by the automatic action of the pendent-trip-bolt, and not only is said lock concealed out of sight of burglars or of any parties who may seek snrreptitiously to open the window, but also the means of tripping the release of the captive bolt to effect the lock and of unlocking the same is also concealed, and that at a remote corner from said `lock where it would be unsuspected by parties outside.

I do not confine myself to a metal cord or cable which, as previously stated, is preferably made of brass wire, for what is termed thel captor-cord in the specification, for it may not only be made of any other suitable material, but also it maybe in the form of a chain instead of a cord.

The keeper-plate 34 has an integral recessbox, into which the lock-bolt springs, which makes a safety-guard around the sprung bolt that protects it from the assaults of burglars, who are thus prevented from boring through the meeting-rail of the sash from the ,outside to the end of said bolt and then forcing it back.

It will be seen that the pivoted quadrant lock-bolt, moving on the arc of a circle, effects a grasping-clutch hold within said safety-boxing of said keeper, and thus clamps the meeting-rails of the sash tight together, and prevents the rattling of the sash from the wind, and also effects a tight joint that is impervious to drafts. It will also be seen that when unlocked either sash may be raised and lowered independent of the other.

I claim as my inventionl. In asash-fastener, the combinationof the spring-lock that fastens 'together the meetingrails of the sash, the captor-cord that captivates the spring-bolt ot' said lock in its disengaged position, and the pivoted captor quadrant-plate that holds said cords, substantially as described.

3. In a sash-fastener, the combination of the spring-lock that fastens together the meetingrails of the sash, the captor-cord 3l, the pivoted captor quadrant-plate 58, the ratchetteeth on said captor-plate, the spring-pawl that engages in said teeth, and the automatic trip-bolt 75, that trips said pawl out of engagement with said ratchet, substantially as described.

4. Inasash-fastener, the combination of the pivoted spring captive-quadrant lock-bolt 21, the captor-cord 3l, that when said lock-bolt is not engaged holds it captive, the spring 27, that when said bolt is released by said cord throws it into its engaged position, the keeper 34E, and the safety-box Sl, the said box having the anti-rattler locking-surface 82, against which said bolt locks, substantially as described.

5. In a sash-fastener, the combination of the countersunk boxing of the spring-lock, embedded in one of the sash-rails, the keeperplate having its safety-boxing 8l embedded in the corresponding sash-rail, the pivoted quadrant-bolt, the spring that projects said bolt into engagement with said keeper-plate, the captor-cord 3l, the captor-plate 58, that holds the initial end of said cord, the serrated rack on said captor-plate, the pivoted pawl 66, whose point when the spring-bolt is held captive engages with said rack, the spring 67, that projects said pawl, the tripbolt 75, having the elongated neck 77, and the trip-boltLcarrier lugs 50, between which IOO IIO

said elongated neck is seated and works, substantially as described.

6. In asash-fastener, the combination of the window-sill, lthe boss 80, embedded in said sill, the upper and the lower sash, the spring-lock countersunk in the 1neetingrail of one sash, the keeper countersunk in the corresponding meeting-rail of the other sash, the Captor-cord 3l, secured to the spring-actuated bolt of said lock, the perforate seat 33, in which said cord is secured, the serrated rack and grooved captor pivoted plate 5S, the perforate seat 62, in which the other end of said Captor-cord is secured, the pivoted spring-pawl which engages with said rack, thetrip-bolt 75, that Vertcally sui-mounts said boss 8O and when the sash is closed strikes the same and trips said spring-lock 8, the Captor-cord 31, that controls the action of the spring-bolt of said lock, to which bolt it is secured, the pivoted captorplate 58 with its serrated rack 65, to `which capter-plate the other end of said cord is secured, the pivoted spring-pawl 66, the automatic trip-bolt 75, the key-seat stem of the journal-shaft of said Captor-plate, and the key that operates the same, substantially as described.
